So we've been using this Zenitel intercom. We use them outside of doors and gates. The user pushes the button, it calls a VOIP phone, the employee picks up and can hit a button to trigger the door or gate to open. Very simple.
The symptom is basically that the button becomes unresponsive. We can communicate with the intercom on the network, configure it, hear audio when its extension is called, etc. Circuit board lights are lit appropriately, power is good, the button to ring is just not functional at all. I can reboot it (POE), but the problem persists.
The thing is that we've had to replace four of this model in the past 12-18 months or so. We're located in the southeast, so it's very humid and we get tropical systems yearly (can mean days of horizontal rain). I assume that's where the issue stems from. The circuit board doesn't appear to have any water intrusion or corrosion, but that's the only thing I can think of that would cause the issue. Our indoor Zenitel intercoms have not had any issues. So it's either weather or poor design. Either way, I need to find an alternative. Does anybody have any tried and true IP/SIP intercom suggestions?
Thanks!
